Materials, grades, finishes and treatments
| Material | Grade / hardness | Finish |
|---|---|---|
| Steel | 45H | Uncoated; Zinc plated clear; zinc plated black |
| Stainless steel A2 | To specify according to ISO 3506-3 | To specify |
| Stainless steel A4 | To specify according to ISO 3506-3 | To specify |
| Nylon | Not applicable | Natural |
45H is a set-screw hardness class according to ISO 898-5, not tensile property class 8.8 or 10.9. For stainless steel, specify the class according to ISO 3506-3. Dueemme confirms material, finish and size in its quotation.

Standards, types and application
The dimensional table refers to ISO 4026. DIN 913 and UNI 5923 are related references: verify the edition and differences before substitution.
Set screws lock by point pressure against the component. They are not intended for tensile loading like headed screws. Assess tightening torque and component strength for the actual joint.
For high-hardness steels with electroplated finishes, assess hydrogen embrittlement and ISO 4042 requirements; post-treatment alone does not guarantee elimination of the risk.
Configure your enquiry
Select the diameter and enter the required length in the specifications, together with material, finish and quantity. Dueemme will confirm supply in its quotation.
The size you need, including custom specifications
Other diameters, lengths, materials and finishes can be assessed on request. For dedicated production, we agree geometry, requirements and minimum quantities with the customer.
